Description

Technical Field

[0001] The present invention relates to a curling device, and more particularly to a gear ring curling device. Background Art

[0002] In the field of mechanical manufacturing, gear rings, as key components in many mechanical devices, are widely used in various industries. The processing quality and production efficiency of gear rings directly affect the performance, stability, and service life of related devices. Among them, the curling process of gear rings is an important link in the manufacturing process of gear rings, and its processing technology and equipment are particularly important for gear ring processing. In the prior art, there are the following problems with gear ring curling devices: On the one hand, in terms of conveying and correcting the workpieces to be curled, traditional devices lack an effective coordination mechanism. Many devices can only simply convey the workpieces to be curled and cannot accurately correct them, resulting in different postures of the workpieces to be curled when entering the curling link, making it difficult to ensure the curling accuracy and quality. Although some devices are equipped with correction structures, the correction wheels are made of ordinary materials and have insufficient friction, so the workpieces to be curled are prone to slipping during the conveying process, which not only affects the conveying efficiency but also may cause scratches on the surface of the workpieces to be curled, reducing the yield rate of products. On the other hand, the curling devices in the prior art adopt simple single-wheel or double-wheel curling structures, which cannot meet the processing requirements of complex gear ring shapes. Moreover, the positions of the curling wheels are fixed and it is difficult to flexibly adjust them according to the requirements of different specifications of gear rings, restricting the versatility of the device. During the curling process, due to the lack of effective limiting measures, the workpieces to be curled are prone to deviation, resulting in poor dimensional accuracy and unqualified roundness of the curled gear rings, seriously affecting product quality. The cutting assembly also has defects. Most traditional cutting devices have simple structures, and it is difficult to accurately control the cutting position. Moreover, the cooperation between the cutting assembly and the curling assembly is not tight enough, and efficient automated production cannot be achieved, with a lot of manual intervention and low production efficiency. In addition, the layout and auxiliary structures of the overall device also have deficiencies. There is a lack of a perfect guiding and auxiliary device, and the workpieces to be curled are prone to being interfered by external factors during the conveying process, resulting in unstable running trajectories. At the same time, the unloading method is unreasonable, and it is difficult to unload the curled workpieces quickly and smoothly after cutting, requiring manual operation, which not only increases the labor intensity but also easily causes safety accidents.

[0003] Therefore, those skilled in the art are committed to providing a gear ring curling device that can effectively solve the above technical problems. Summary of the Invention

[0038] The optimal working principle of the present invention is as follows: Place the workpiece to be bent at the first guiding and driving assembly 2. The first guiding and driving assembly 2 includes a number of first driving and correcting wheels 18 and a second driving and correcting wheel 19 directly below them. A correcting channel 20 is formed between the two, and anti-slip ridges 21 made of rubber material are provided on the wheels. The power driving box 7 drives the first driving and correcting wheel 18 and the second driving and correcting wheel 19 to rotate, increasing the friction force by using the anti-slip ridges 21 to correct the workpiece to be bent, keeping it in the correct posture during the conveying process, and conveying the workpiece to be bent to the bending assembly 3; the workpiece to be bent (not shown in the figure) is conveyed to the bending assembly 3. The bending assembly 3 includes a first bending wheel 22, a second bending wheel 23, and a third bending wheel 26. Bending limit grooves 27 are provided on the outer edges of the three bending wheels. The positions of the first bending wheel 22, the second bending wheel 23, and the third bending wheel 26 cooperate with each other. The upper end of the second bending wheel 23 is lower than the lower end of the first bending wheel 22, and the upper end of the third bending wheel 26 is lower than the upper end of the first bending wheel 22 and the lower end is lower than the upper end of the second bending wheel 23. During the rotation of the wheels, the workpiece to be bent is gradually bent into the required shape under the restriction of the bending limit groove 27. In addition, the rear ends of the three bending wheels are respectively rotatably connected to the positioning shafts 28. The positioning shafts 28 can be adjusted in the front-rear direction along the positioning seats 6 and locked by the locking nuts 29, and the positions of the bending wheels can be adjusted according to different bending requirements; the bent workpiece is conveyed to the cutting assembly 5. One end of the adjusting seat 30 of the cutting assembly 5 is hinged to the positioning seat 6, and the positioning screw 31 at the other end passes through the arc-shaped opening 32 on the positioning seat 6 and is positioned by the positioning nut 33. The center point of the arc-shaped opening 32 coincides with the hinge point, which is convenient for adjusting the position of the cutting assembly 5. A cutting port 37 is provided on the cutting seat 36 of the adjusting seat 30. The cutting knife in the cutting port 37 is driven by a power source 38. The power source 38 is arranged outside the cutting seat 36. When the bent workpiece reaches the cutting position, the power source 38 drives the cutting knife to act to cut the bent workpiece. The bent workpiece rolled into a circle is sleeved on the unloading guiding rod 70. After being cut by the cutting knife, the bent workpiece slides along the length direction of the unloading guiding rod 70. In actual use, a collection box or a collection cart can be provided below the unloading guiding rod 70 to facilitate the collection of the unloaded bent workpieces; As a further preference, a vertical plate 50 is provided on the suspended extension seat 39 on one side of the base 1 in the present invention. There is a first adjustment opening 51 on the vertical plate 50. The upper guide wheel 52 at the front end and the lower guide wheel 53 below are arranged in a staggered manner, and there are guide limit grooves 55 at the edges. The first fixed shafts 56 at the rear ends of the upper guide wheel 52 and the lower guide wheel 53 are inserted through the first adjustment slider 57. The first adjustment slider 57 slides at the first adjustment opening 51 and is positioned by a nut, so that the position of the guide wheel can be adjusted, which plays an auxiliary guiding role for the workpiece to be bent during the conveying process. The adjustment screw rod 60 on the fixed plate 58 inside the vertical plate 50 cooperates with the second adjustment slider 61. The lower ends of the two first rotating cylinders 62 and the two second rotating cylinders 63 are rotatably connected to the second adjustment slider 61 and are arranged in a staggered manner, further assisting in the conveying and positioning of the workpiece to be bent. The upper end of the limit cylinder 65 outside the vertical plate 50 is rotatably connected to the top block 66, and the lower end positioning column 67 is adjustable and limited at the long strip opening 68 of the suspended extension seat 39; The above solves the problem that the workpiece to be bent is in a straight line state at the beginning of bending. During operation, first place one end of the workpiece to be bent between the two limit cylinders 65. At this time, the operator applies a thrust by hand to push the workpiece to be bent through the gap between the lower guide wheel 53 and the upper guide wheel 52 in sequence. Since the guide limit grooves 55 are provided at the edges of the upper and lower guide wheels and they are arranged in a staggered manner, it can effectively guide the workpiece to be bent forward and ensure the accuracy of its running track. Then, the workpiece to be bent will pass between the two first rotating cylinders 62 and the two second rotating cylinders 63. These two groups of rotating cylinders further guide and position it to prevent the workpiece to be bent from shifting during the conveying process. After passing through the above-mentioned guiding structure, the workpiece to be bent is sent to the first guiding drive assembly 2. At this time, the first guiding drive assembly 2 starts to play a role. Driven by its own power, it continuously conveys the workpiece to be bent towards the bending assembly 3. Through the above structural settings, before the workpiece to be bent enters the first guiding drive assembly 2, it can be guided in multiple links and in multiple directions, ensuring that the workpiece to be bent can enter the subsequent processing link in the correct posture and stable state, making the bending operation proceed more smoothly.
